like letters on the drawings representing like parts.

This invention relates to weather-indicating devices; and it has for its object the production of a simple, cheap, and attractive article which can be readily used in connection with advertising matter, if desired, and

ywhich by means of a color-index shows at a glance the nature of the weather indication.

' Figure 1 is a plan view of a weather-indieating device embodying one form of my invention, and Fig. 2 is another embodiment of my invention.

My invention consists in an indicator,\vhich is a piece of suitable material, such as cloth or paper, impregnated with a solution of chlorid of cobalt, and an accompanying colorindex, the latter consisting of a plurality of` divisions or panels severally colored to correspond to the various colors assumed by the indicator under dierent conditions of the Weather, so that an instants comparison of the indicator and color-index will disclose the weather condition.

Referring to Fig. 1,`a card, board, or other suitable support A has attached to it a piece of material b, such as paper or cloth, impregnat'ed with a solution of chlorid of cobalt and shown in Fig. 1 as semicircular in shape, attached at bx along the straight side to the support A. cator b is located the color-index, consisting of a plurality of panels c c' c2, shown as sectors to complete the semicircle, the panels being severally colored to correspond to the color assumed by the indicator under different conditions of the weather-that is, the panel c would be blue, indicating fair weather, panel c light blue-gray, and panel o? pink,

Immediately adjacent the indi,-

said colors when assumed by the indicator b denoting fair weather, change, and storm, respectvely.

By making a figure of definite symmetrical shape with the indicator and color-index a very attractive appearance is given to the device, and it is. simple, cheap to manufacture, and very easily read.

In Fig. 2 the general figure is a rectangle, the indicator d being oblong and equal to substantially one half of the ligure, the other half being divided into three equal and symmetrical panels f f f2, colored blue, bluegray, and pink, respectively, but the panels are oblong instead of sectors, as in Fig. 1.

If desired, the Words Fair, Change, and Storm may be delineated on the several panels, as Shown.

Obviously the shape of the panels and indicator is not restricted to that herein shown, for any arrangement and shape may be used, provided a color-index is used in connection with the indicator, said index being composed of a plurality of contrasted colors corresponding severally to the colors assumed by the indicator under dierent conditions of the weather.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A Weather-indicating device consisting of a chemically-prepared indicator, and an 'adjacent color-index composed of a plurality of contrasted colors to correspond respectively to the several colors assumed by the indicator under different conditions of the weather.

. 2. A weather-indicating de'vice consisting of a card, a chemically-prepared piece of'ma terial secured thereto, and a color-index on the card adjacent the edge of the said material, the index being composed of a plurality of panels severally colored to correspond to the different colors assumed by the material in fair, cloudy and stormy weather.

3. A weather-indicating device consisting of a card, a chemically-prepared semicircular piee'ef secured thereto, and a, plu- In testimony whereof I have `signed my rality of adjacent secta-shaped panels eolname to this speolention in the presence of ored to oorrespond to the various colors nstwo` subscribing witnesses. 4 sumed by the material under derent eoxdi` FRED A.
